The chimney specialists at Detroit City Sweep unclog flues of soot and other buildup that might be preventing proper ventilation and posing a safety risk. After laying down a protective barrier to prevent damage to carpeting or interior surfaces, the sweep sets about brushing the chimney from top to bottom. Over the course of the visit, which can last up to 45 minutes, he also performs a 26-point safety inspection and, once finished, informs the homeowner when the fireplace is again safe for use. In keeping with the unclogging theme, the team also performs dryer vent cleanings and gutter cleaning, wherein they remove sticks, leaves, and other detritus from the gutter so that rainwater might run off unimpeded. Detroit City Sweep also offers masonry repair services.
